Application filed July 20, 1906. Serial No. 327,021.

To all whom it may concern:

Be it known that I, CHARLES WAGNER, a citizen of the United States, anda resident of the city of New York, borough ofManhattan, in the countyand State of New York, have invented a new and Improved Machine forCleaning Inking-Rollers, of which the following is a full, clear, andexact description.

The invention relates to machines employed for cleaning inking rollers,mainly such as are leather covered and used in lithographic and otherprinting machines.

The object of the invention is to provide a new and improved machine forcleaning inking rollers which is simple and durable in construction andarranged to permit of conveniently and quickly placing the inking rollerin osition for cleaning the same, to thorough y and quickly clean theinking roller of the ink and other undesirable matter, and to leave theperipheral surface of the inking roller in condition for pro erlyreceiving and applying the printers in r to the surface to be inked whenthe inking roller is used in the printing machine.

The invention consists of novel features and parts and combinations ofthe same, which will be more fully described hereinafter and then ointedout in the claims.

A practica embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1'is a plan View of the improvement; Fig. 2 is a side elevationof the same;

Fig. 3 is an enlarged end elevation of the improvement; Fig. 4 is anenlarged side elevation of part of the scraper; Fig. 5 is a plan view ofthe same; Fig. 6 is an end elevation of part of the scraper and itssupport and guide, the latter being shown in section; Fig. 7 is a sideelevation of the means for reciprocating the brushes; Fig. 8 is anenlarged transverse section of the inking roller in osition on thesupporting and driving rol ers and the brushes for cleaning the inkingroller, and Fig. 9 is a plan View of the same.

On a suitably constructed frame A are j ournaled the revolublesupporting rollers B, B disposed parallel one with the other and adaptedto receive support and rotate a printing roller C to be cleaned of itsrinters ink by the use of a brushing device D and a scraping device E,both devlces acting simultaneously on the printing roller 0 while thelatter is rotated and while use is being made of benzin, turpentine andother cleaning agent poured over the printing roller-C during the timethe machine is in action, as hereinafter more fully described. In orderto rotate the supporting rollers B and B their shafts B B are providedat one end with worm wheels B B in mesh with worms F, F secured on atransversely extending shaft F journaled in suitable bearings arrangedon one end of the frame A. Onthe shaft F is secured a clutch member F(see Fig. 3) adapted to be engaged by a clutch member H mounted torotate loosely on the shaft F and provided with apulley H connected by abelt with other machinery, for imparting a continuous rotary motion tothe said pulley H. The clutch member H is engaged by a shifting lever Hfulcrumed at H on the main frame A and under the control of theoperator, for throwing the clutch member H into engagement with theclutch member F to drive the shaft F and consequently the supportingrollers B and B by the worms F, F and the worm wheels B B Now, it isevident that as the printing roller C extends between and rests on therotating supporting rollers B and B, it is evident that a rotary motionis given to the printing roller C from the supporting rollers B and B. Aspring H interposed between the clutch members F and H serves tonormally hold the clutch member H out of engagement with the clutchmember F The brushing device D, shown in detail in Figs. 8 and 9,consists of pairs of brushes D, D engaging op osite sides of theprinting roller C above tie supporting rollers B, B, and the saidbrushes D, D are provided with arms D D mounted to swing on alongitudinally extending rod D held on arms D fulcrumed on a rod Ijoui'naled in suitable bearings on one side of the frame A, the said rodI carrying at one end an arm I for engaging the shoulder end of theshaft C of the printing roller C, to hold the latter againstlongitudinal movement while the machine is in operation. The brushes D,D of each pair of brushes are pressed towards each other by a spring D,so as to hold the bristles of the brushes D, D with sufficient force incontact with the peripheral surface of the rotating printing roller C,to cause a thorough cleaning of the same. The brushing device D has areciprocating movement in a longitudinal direction and for this purposethe following device is provided: The arms D D of the brushes D, Dbesides being mounted to swing transversely on the rod D movelongitudinally with the same by the use of collars D secured on the rodD and engaging opposite ends of the hubs of the arms D D On the rod D issecured an arm D carrying a friction roller D extending into a segmentalguideway J formed on the upper or free end of a rocking lever Jfulcrurned at J on the main frame A. The rocking lever J is pivotallyconnected with the eccentric rod J of an eccentric J held on the clutchmember F so that when the latter is rotated a longitudinal swingingmotion is given to the rocking lever J which by the guideway J andfriction roller D imparts a longitudinal reciprocating motion to the rodD and consequently to the brushes D, D WVhen it is desired to move thebrushes D, D out of engagement with the printing rollerC, it is onlynecessary for the operator to swing the rod D rearwardly, whereby thefriction roller D travels in the segmental guideway J and consequentlythe brushes D, D although out of engagement with the printing roller Ckeep on reciprocating but are out of the path of the printing roller C,to allow removal of the latter from the supporting rollers B, B and thereplacing of another one without stopping the machine. The amount ofmovement given to the brushes D, D in a longitudinal direction is suchthat the range of movement of one brush overlaps the range of movementof the neXt adjacent brush and hence each and every part of theperipheral surface of the rotating inking roller C is brushed to insureremoval of all the undesirable matter.

The scraping device F, shown in detail in Figs. 4, 5 and 6, is arrangedas follows: A traveling endless chain E is provided at intervals withscrapers E extending transversely and segmental in form, to fit the peripheral face of the inking roller C, and the said endless chain passesaround segmental sprocket wheels E E, of which the former is secured onthe shaft F and the sprocket wheel E is secured on a shaft E journaledin bearings E held longitudinally adjustable on the rear end of theframe A (as plainly indicated in Fig. 1), to give the desired tension tothe upper run of the endless chain E. Each scraper E is provided with apivot-pin E eral face of the inking ro ler C.

journaled in a block-link E of the endless chain E, to allow the scraperE to readily turn, with a view to pro erly fit the peri h- It is unerstood that for inking rollers of a diameter less than that for whichthe scraper is fitted, the scraper E assumes an oblique positionrelative to the chain E, to properly fit the smaller inking roller. Theupper run of the chain E travels in a longitudinal guideway K, havingdepending pins K slidingly engaging bearings K held on the frame A, andthe under side of the guideway K rests on the peripheral faces ofeccentrics K secured on transverse shafts K, journaled on the main frameA, and on the outer ends of the said shafts K are secured worm Wheels Kin mesh with worms K attached to a longitudinal shaft K journaled on themain frame A and provided at one end with a hand-wheel K under thecontrol of the operator, to permit the latter to turn the shaft K theworms K, the worm wheels K the shafts K and the eccentrics K to raise orlower the guideway K and the upper run of the chain E and scrapers Eaccording to the direction in which the hand wheel K is turned. Thus, bythe arrangement described, the scrapers E can be moved into properrelation to the peripheral face of the inking roller C, to thoroughlyscrape the same, it being understood that each scraper E is in contactwith the inking roller C throughout the length thereof and while the inkroller is rotated by the sup porting rollers B ,B and the brushingdevice D is in action and holds the inking roller down onto the suporting rollers B, B. In order to collect al the matter removed from theinking roller C a pan L is provided, preferably formed on the bed of theframe A. and extending throughout the length thereof, be low the rollersB, B, the brushing device D and the scraping device E, so that all thematter loosened and removed from the inking roller drops down into thepan L, to flow from the latter by way of one of a number of pipes N intoa corres onding collecting tank 0, the several tanks 8 being mounted onthe lower portion of the frame A. Each of the pipes N is provided with avalve i and each tank 0 is provided with a faucet P for drawing ofi theink. Use is made of several tanks 0 and valved pi es N to allow ofrunning all the ink of one 00 or into one tank 0, it being understoodthat in successively cleaning differently colored inking rollers it isdesirable to keep the removed colors separate, to facilitate theseparation of the cleansing agent used from the tank.

main shaft F is running and the printing roller C is supported on thesupporting rollers B and B and the brushes D, D are in engagement withthe peripheral face of the printing roller C and the scraping device isin action, as reviously explained, then the inking rollerC is rotatedand the brushes D, D are reciprocated and held in firm frictionalcontact with the peripheral surface of the printing roller C by theaction of their springs D andtheir own weight. It will be seen that asthe printing roller C is rotated and the brushes D, D reciprocatelengthwise on the peripheral face of the printing roller C, a thoroughbrushing of the entire peripheral surface of the printing roller takeslace, it being understood that a suitable (Heansing agent such asbenzin, turpentine or the like is poured over the top of the printingroller C to assist the brushes in completely removing every vestige ofthe ink on the inking roller. At the same time that the brushing actiontakes place the scrapers E travel lengthwise and in engagement with theperipheral surface of the inking roller C at the bottom thereof, toscrape the peripheral surface, of the inking roller from one end to theother and practically in aspiral direction as the printing roller C isrotated, while the scrapers E travel in the direction of the length ofthe rotating inking roller. By the combined action of the cleansingagent the brushing device D and the scraping device E a thoroughcleaning of the inking roller C takes place, and at the same time theperipheral face thereof is left in the proper condition for receivingthe ink when the roller is again used in the printing machine for itslegitimate purpose. WVhen the inking roller C has been cleaned, asdescribed, then it is only necessary for the operator to take hold ofthe rod D and swing the same rearwardly without, however, disengagingthe friction roller D on the segmental guideway J, and when the brushesare thus moved to one side and away from the inking roller C the lattercan be readily moved lengthwise to disengage its shoulder .shaft C fromthe arm I, after which the inking roller can be removed and a new one tobe cleaned can be placed in position on the supporting rollers B and B.The operator now again swings the rod D downward to engage the brushesD, D with the peripheral surface of its inking roller, and the abovedescribed operation is repeated, that is, the machine is kept runningcontinually while removing a clean inking roller and replacing the sameby one to be cleaned. lVhen it is desired to stop the machine theoperator can conveniently do so by shifting the clutch member H out ofmesh with the clutch member F. The impuritiesremoved from the printingroller C drop down into the pan L and flow by the open pipe N into thecorresponding tank 0 in which the benzin or other cleaning liquidreadily separates from the ink and the cleansing liquid can be withdrawnfrom time to time through the faucet P.

The'machine shown and described is comparatively simple in constructionand arranged to permit of thoroughly cleaning a large number of inkingrollers C in a comparatively short time.
